This SAE Recommended Practice includes wheel mounting elements subject to standardization in a series of industrial and agricultural disc wheels. The disc may be reversible or nonreversible and concave or convex (See Figure 1 and Table 1).
This part of SAE J551 specifies on-board transmitter simulation test methods and procedures for testing passenger cars and commercial vehicles. The electromagnetic disturbances considered in this part of SAE J551 are limited to continuous narrow band electromagnetic fields. SAE J551/1 specifies general, definitions, practical use, and basic principles of the test procedure.
This SAE Recommended Practice applies to rigid bumper or rigid structure points and flexible components of passenger cars, multipurpose passenger vehicles, and light trucks. This document is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances.
This document describes the collection of IUMPR data required by the Heavy Duty On-Board Diagnostic regulation 13 CCR 1971.1 (l)(2.3.3), using SAE J1939-defined messages incorporated in a suite of software functions.
This SAE Standard provides a definition of a rainflow file format. This type of simple text file would contain all relevant information about the rainflow cycle content of a time history. Included information are Comments, Signal Range, Signal Mean, Number of Cycles, Signal Maximum, Signal Minimum. Rainflow cycle counting has become the most accepted procedure for identifying material fatigue relevant cycles in complex variable amplitude load time histories. The cycle counting methods account for the effects of material plasticity and material memory of prior deformation, and the resulting compressed history information is used by durability analysts to estimate the effects of a given service or test history.
